Dr Geoffrey Beadle says the drug letrozole, sold as Femara, is used to prevent the return of cancer in patients who have already undergone certain other treatments.
He says the medication will be cheaper when a federal subsidy comes into effect next month.
"Its current costs are beyond the reach of some women with breast cancer and by subsidising the cost through the Pharmaceutical Benefit Scheme [PBS], it is now a drug that is accessible for all women for who it's indicated," he said. © 2007 Australian Broadcasting Corporation
